What is the essence of bitcoin mixers? Does it really make sense to use them only to those who conduct illegal activities?
You should definitely avoid them if you have clean Bitcoins. There are two reasons for that. First is they are very expensive. You will get much less out than you put in. Second is you might end up with Bitcoins someone pay to hire a murder with.
Binance has a negative attitude to such bitcoins that were previously received through the mixer. And all funds are blocked by the exchange. Until now, there was no such practice of confiscating such bitcoins from the owner, they were simply returned to the sent address. This describes a case that occurred in December last year:
